BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a pest controller for killing orrepelling pests such as insects harmful to persons. More particularly,it relates to a pest controller available without a fire, an electricityor the like. It further relates to a method for controlling peststherewith.

2. Background Art

Pest controllers such as mosquito coils and electric mosquito mats areconventionally used for killing or repelling noxious organism such asharmful pests so as to avoid them.

A various kind of pest controllers having different structures areproposed as the controllers available without a fire, an electricity orthe like.

Japanese patents Laid-Open No. Hei. 09-289855, No. Hei. 09-308421 andNo. Hei. 11-255604 disclose the known art relating to the presentinvention.

The conventional pest controller that is disclosed in Japanese patentLaid-Open No. Hei. 09-289855 includes cylindrical paper or the like thatare bundled and contain a pesticidal or pest repellent compound that isvolatile at a normal temperature. The document also discloses astructure including papers rolled or bent with spaces therebetween thatcontains a pesticidal or pest repellent compound being volatile at anormal temperature.

The conventional pest controller that is disclosed in Japanese patentLaid-Open No. Hei. 09-308421 includes a foldable member made of paperhaving a number of vents that contains a pesticidal or pest repellentcompound being volatile at a normal temperature.

The conventional pest controller that is disclosed in Japanese patentLaid-Open No. Hei. 11-255604 includes a balloon member made of such asrubber that carries a pesticidal or pest repellent compound beingvolatile at a normal temperature.

However, the conventional controllers are difficult to use and to bemade.

That is, the conventional controllers have pesticidal or pest repellentcompounds being volatile at a normal temperature on such as paper andrubber, which are exposed to open air so as to volatilize pesticidal orpest repellent ingredients during use. Therefore, users are often liableto unintentionally contact part of paper and rubber containing thepesticidal or pest repellent ingredients.

The controllers disclosed in Japanese patent Laid-Open No. Hei.09-289855, which are of types such as bundling the cylindrical papers,rolling the papers with spaces, and bending the papers with spaces, aretoo bulky to conveniently carry.

The controller disclosed in Japanese patent Laid-Open No. Hei. 09-308421is likewise too bulky to conveniently carry, though it is to open thefolded papers in use.

Further, the conventional controllers are difficult to maintain andcontrol pesticidal effects. That is, as for the conventionalcontrollers, the amount of pesticidal or pest repellent ingredientscontained in the papers and the rubbers is limited by their sizes.Consequently, a portable controller is difficult to maintain apesticidal effect. It is not also easy to change a volatile area,resulting in being difficult to adjust the pesticidal effect.

It is therefore an object of the present invention made in view of theproblems and drawbacks described above to provide an advanced pestcontroller that contains pesticidal or pest repellent ingredients, thatreduces the possibility of unintentional contact with the ingredients,that is easy to carry, and that is able to maintain a sufficientpesticidal effect in a portable size.

DISCLOSURE OF THE INVENTION

An aspect of the present invention proposed for achieving the aimdescribed above is a pest controller including a portable containerholding a chemical substance therewithin, wherein the container includesa substance exposing portion (or a substance releasing portion) forexposing the chemical substance held therein to outside, and a cover forsealing the substance exposing portion, the chemical substancecontaining an active ingredient with a pest-controlling effect, and theactive ingredient being volatilizable at a normal temperature. Herein,the term “chemical substance” includes liquid, gel, and solid substanceof an active ingredient itself, and a liquid substance wherein theactive ingredient is dispersed in a solvent. The active ingredient witha pest-controlling effect denotes a chemical that has insecticidal orinsect repellent effects against harmful insects by volatilization.

Since the present aspect includes a container holding a chemicalsubstance therewithin, wherein the container includes a substanceexposing portion for exposing the chemical substance held therein tooutside, and a cover for sealing the substance exposing portion, thechemical substance containing an active ingredient with apest-controlling effect, and the active ingredient being volatilizableat a normal temperature, volatilization of the active ingredient with apest-controlling effect from the substance exposing portion makes itpossible to kill and/or repel harmful insects. It is also possible to beconstructed without a container.

The pest controller of the invention is carried to use, due to itsportability.

By the pest controller of the invention, the chemical substance isaccommodated within the container, so that the possibility ofunintentional contact with the ingredients is reduced.

Further, adding structure by which a size of a substance releasingportion for adjusting a volatilization is changeable enables apest-controlling effect to be adjusted.

It may be also constructed in such a manner that the chemical substanceis contactable with an open air at the substance exposing portion so asto be released into the air therefrom when the cover is open. In such astructure, when the cover is open, the chemical substance is contactablewith open air at the substance exposing portion so as to be releasedinto air therefrom. In the present aspect, when the substance exposingportion is sealed, the active ingredient does not volatilize, so thatwasteful volatilization of the active ingredient can be reduced duringnon-use.

It may be also constructed in such a manner that the substance exposingportion is provided with an applicator for applying the chemicalsubstance onto a body. In such a structure, the chemical substance isapplied through the substance applicator of the controller, and further,the active ingredient with a pest-controlling effect is released from anapplied spot, so as to kill and/or repel harmful insects. Applying thechemical substance to a wide area volatilizes the chemical substancefrom the wide area and brings a high chemical substance density at asurrounding area.

It may be also constructed in such a manner that the substance exposingportion is constituted by a member selected from a group consisting of aporous body, a fibrous bundle and a member with a through-hole, so thatthe chemical substance is exposed on a surface thereof. In such astructure, the use of liquid active ingredient makes a volatilization ofactive ingredient easy without dispersion outside. Further, the presentaspect may be preferably employed in a structure to apply the chemicalsubstance, thereby readily applying the substance exposed to thesubstance exposing portion to a body.

The substance exposing portion may be constituted by a member selectedfrom a group consisting of a ball and a roller both being rotatable.Such a structure achieves an easy application of the chemical substance.

The chemical substance may be directly held within the container. Insuch a structure, it is easy to fill the substance to the container andalso fill in large quantities.

It may be constructed in such a manner that the chemical substance has afluidity and that the container further includes a substance storagecontaining the substance and a substance lead-out member providedbetween the substance storage and the substance exposing portion so asto lead the substance out of the substance storage through the substancelead-out member to the substance exposing portion. In such structure, itis easy to lead the substance out of the substance storage to thesubstance exposing portion.

The container may accommodate a substance retaining member, the chemicalsubstance being capable of flowing, and retained in the substanceretaining member. In such a structure, the chemical substance does notmove within the container in carrying the controller. The substanceretaining member may be a member not integral with the container,thereby ensuring that the substance retaining member may be exchanged bya cartridge replacement system.

The substance retaining member may be made of fiber. Such a structureallows the substance retaining member to hold plenty of chemicalsubstance.

The container may include a storage tank and a temporary receptacle forthe chemical substance. In such a structure, dependent on a pressurechange in the container, if and when the pressure rises, the substanceis stored in the storage tank, so as to prevent the substance from awasteful volatilization and a leakage.

The container may be of a cylindrical shape, and the substance exposingportion may be placed at an end of the container of cylindrical shape.In such a structure, since the container is of a cylindrical shape andthe substance exposing portion is placed at an end of the cylindricalcontainer, it is easy to make the container and easy to carry it.

It may be constructed in such a manner that the container includes acontainer body holding the chemical substance therewithin, that the bodyaccommodates a substance retaining member adapted to absorbing thechemical substance, the substance retaining member soaked with thechemical substance, and that the body is provided with the substancelead-out member adapted to leading the chemical substance out of thebody, a proximal part of the substance lead-out member being in contactwith the substance retaining member and a distal part of that beingexposed out of the body. Such a structure enables the substance tovolatilize through the substance lead-out member.

The substance exposing portion may be adapted to adjusting an exposingarea of the chemical substance. The substance exposing portion may havea window, an opening area of which is changeable. Such structures enablean amount of volatilization of the substance to be readily adjusted.

It may constituted in such a manner that the container includes acontainer body holding the chemical substance therewithin, so as to holda liquid chemical substance with a fluidity within, and that the body isprovided with a substance lead-out member adapted to lead the chemicalsubstance out of the body and a valve system, the valve system beingopen by a predetermined operation, whereby the chemical substance insidecreeps through the substance lead-out member so as to be exposed out ofthe body. Such a structure employs the valve system, thereby reducing anexcess creep of chemical substance. That is, by the present aspect,appropriate amount of chemical substance can creep when needed.

The container may include a substance holder holding the chemicalsubstance with fluidity in a sealing condition therewithin, thesubstance holder having a follower moving according to a consumption ofthe chemical substance. The follower may be gel. In such structures, thefollower protects the chemical substance from easy flowout and contactwith the air, achieving less deteriorates.

It may be constituted in such a manner that the container includes acontainer body holding the chemical substance therewithin so as to holda liquid chemical substance with a fluidity therewithin, that the bodyis provided with a substance lead-out member adapted to leading thechemical substance out of the body, and that to the substance lead-outmember a substance releasing member separately provided is attachable.Such a structure volatilizes the chemical substance from larger area.

It may be constituted in such a manner that the container includes acontainer body holding the chemical substance therewithin and anattachment detachable from the body and attachable to the body in atleast two ways of attachment, so as to hold a liquid chemical substancewith a fluidity therewithin, and that the body is provided with asubstance lead-out member adapted to leading the chemical substance outof the body, the attachment being provided with a cover for sealing thesubstance lead-out member, and a substance releasing member for helpingrelease of the chemical substance, the substance lead-out member beingsealed by attaching the attachment to the body in a particular position,the chemical substance being supplied to the substance releasing memberfrom the substance lead-out member by attaching the attachment inanother particular position. Such a structure makes it possible torelease and seal the chemical substance depending on a position of theattachment. Further, by the present structure, the chemical substancevolatilizes from the substance releasing member, so that largervolatilizing area can be obtained.

The container may have a deformable portion so that the chemicalsubstance inside the container will be brought out by pressing thedeformable portion. Such a structure enables the liquid chemicalsubstance to be brought out with an easy operation.

The container may have a pressurizer for increasing the inner pressureof the container so that the chemical substance is brought out. In sucha structure, the pressurizer presses the inner space of container tobring out the chemical substance, thereby making sure more to bring outthe substance.

Another aspect of the present invention is a pest controller including acontainer holding a chemical substance of columnar shape therewithin,wherein the container has an opening communicating with the inside ofcontainer, and a cover for sealing the opening from outside, the coverbeing adapted to opening and shutting, the chemical substance beingadapted to be propelled out of the container through the opening, thechemical substance containing an active ingredient with apest-controlling effect, the active ingredient being volatilizable at anormal temperature. In such a structure, an operation of propelling outbrings out the chemical substance from the opening. It is thereforepossible to apply the substance brought out from the opening to a bodyand to volatilize the active ingredient directly from the substancebrought out for controlling pests. In case of controlling pests byvolatilizing the active ingredient directly from the substance broughtout, a change of length brought out of the container may adjust apest-controlling effect.

The container may include a container body, an operating portionturnable relative to the body, and a screw positioned in the body, thescrew being adapted to turning in response to a turn of the operatingportion, so that a force generated by the screw makes the chemicalsubstance be propelled out of the body. In such a structure, since thescrew turns in response to a turn of the operating portion, so that thechemical substance is propelled out of the body by a force generated bythe screw, easy construction achieves propelling out.

Still another aspect of the present invention is to provide a pestcontroller including a solid chemical substance formed in a particularshape and containing an active ingredient with a pest-controllingeffect, the active ingredient being volatilizable at a normaltemperature, and a coat formed on the surface of the chemical substanceso as to be exfoliated by a predetermined amount. In such a structure,if and when the exposing portion is reduced by consumption, removing thecoat increases the exposing portion.

Yet another aspect of the invention is to provide a pest controllerincluding a container holding therewithin a chemical substance formed inthe shape of a rod, wherein the chemical substance contains an activeingredient with a pest-controlling effect, the active ingredient beingvolatilizable at a normal temperature, wherein the container has apusher for pressing the chemical substance, and a chuck being adapted toholding and releasing the chemical substance so that the chemicalsubstance is pushed out by pressing the pusher and held by the chuck,thereby the chemical substance is prevented from moving back. Such astructure makes sure to propel out the chemical substance and preventsit from moving back during use, thereby being easy to apply it.

The pest controller may include a heater for heating the chemicalsubstance. Such a structure makes it possible to volatilize the chemicalsubstance further more.

The container may include a container body holding the chemicalsubstance therewithin, and a cap being separable from the body and beingattached to the body so as to constitute the cover. In such a structure,there is provided with a cap being attached to the body so as toconstitute the cover, so that the cover with simple structure isprovided.

The container may be equipped with a holder for attaching the controllerto a body. In such a structure, the container is equipped with theholder, thereby ensuring that the pest controller can be carried for useby hanging.

It may be constituted in such a manner that the container is of atabular shape, and that the substance exposing portion is of a planarshape. Such a structure is provided with the substance exposing portionof wide area with a small size of the pest controller.

The cover for sealing the substance exposing portion may include adeformable sheet, the sheet being removable, so that the cover ofsubstance exposing portion is detached by removing the sheet. In such amanner, a change of area from which the sheet is removed adjusts avolatilization of the chemical substance.

The container may be adapted to be directly worn and/or attached toclothes. Such a structure makes it easy to carry the pest controller.

The container may have an attaching member for attaching the controllerto a body. Such a structure makes it easy to attach the pest controlleronto clothes. A body to which the controller is attached may be clothesor any article in a spot for controlling pests, for example, an outdoortent.

At least a part of the container may be made of biodegradable resin. Insuch a structure, since at least a part of the container is made ofbiodegradable resin, it is possible to dispose of wastes of the pestcontroller by biodegradation.

The pest controller may include a cover for sealing the substanceexposing portion, wherein the cover comprises a deformable sheet, thesheet being removable, so that the cover of substance exposing portionis detached by removing the sheet. Such a structure makes it possible touse the controller readily by detaching the cover of substance exposingportion.

Yet still another aspect of the present invention is to provide a pestcontroller including a portable and airtight bag, wherein the bag isadapted to release a sealing condition by releasing an airtightness, andwherein the bag accommodates a fiber soaked with a chemical substance,the chemical substance containing an active ingredient with apest-controlling effect against harmful pests for human body, the activeingredient being volatilizable at a normal temperature. The controllercan be used only by releasing the sealing condition.

A further aspect of the present invention is to provide a pestcontroller including a portable and air-permeable bag, wherein the bagincorporates a chemical substance, the chemical substance containing anactive ingredient with a pest-controlling effect against harmful pestsfor human body, the active ingredient being volatilizable at a normaltemperature. The controller makes it possible to control pests bycarrying the bag.

It may be constituted in such a manner that the chemical substance isliquid and that the bag accommodates a substance absorbing member soakedwith the chemical substance. Such a structure makes it possible toaccommodate even the liquid chemical substance in the air-permeable bag.

The bag may be equipped with an adhesive member being attachable tohuman body or clothes. In such a structure, the controller is fixed toclothes readily.

The active ingredient may have a vapor pressure at 25° C. by Donovanmethod within a range of 1×10⁻⁵ mmHg to 5×10⁻³ mmHg, thereby being aptto volatilize and bringing a sufficient pest-controlling effect withoutmaking the substance releasing portion big.

The active ingredient may be a pyrethroid compound, thereby bringing anexcellent pest-controlling effect against insects and so on with smallamount and a high safety for human when the controller is used.

The chemical substance may contain a sublimable dyestuff. In this case,the dyestuff sublimates with the active ingredient of the substance,thereby informing an effective period of the substance.

The pest controller described above gets rid of pests. A method forcontrolling pests is carried out by opening the cover of the pestcontroller at a spot for controlling pests so as to volatilize thechemical substance containing the active ingredient into the air fromthe substance releasing portion. Another method is carried out bycontacting the applicator with a spot for controlling pests to apply thesubstance on the spot so as to volatilize the substance containing theactive ingredient into the air. These methods for controlling pests withthe pests controller get rid of pests.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Now typical embodiments of the present invention will be describedbelow, making reference to the accompanying drawings.

Pest controllers described below are all portable and preferably apocketable size. More particularly, it is preferable to have a length ofabout 150 mm or less and a weight of 50 g or less, and more preferably,a length of about 120 mm or less and a weight of 20 g or less.

A pest controller 1 provided in a first embodiment of the presentinvention has a structure shown in FIG. 1. The pest controller 1 hassuch a structure as a marking pen.

The pest controller 1 includes a container 8. The container 8 consistsessentially of a container body 11 of a cylindrical shape and a cap 10attached to a distal end of the body 11. The length of container 8 isabout 150 mm. The body 11 is equipped with a clip 12.

The clip 12 is a holder for attaching the controller to a foreign bodyand provided on a trunk of the body 11. Therefore, a cloth such as apocket of garments may get sandwiched between the clip 12 and the trunkof the body 11. The attachment of the pest controller 1 onto garmentsprevents it from falling off from users wearing the garments in case ofcarrying it.

The container 8 and the cap 10 are preferably made of such materials asunaffected even if being in contact with a chemical substance 22described below. More particularly, they can be made of any resin suchas polyethylene resin, polypropylene resin, polyamide resin, polystyreneresin, polyacetal resin, and polyethylene terephthalate resin, or of anymetal such as aluminum and stainless steel, though polyamide resin maybe preferably used.

Further, the use of biodegradable plastic as materials of the container8 and the cap 10 is environment friendly because the container 8 and thecap 10 are degradable by bacteria or the like. Biodegradable plasticsinclude starch-added plastics to which a starch is added,microorganism-produced plastics composed of polyester generated bymicroorganism, and synthetic plastics made by chemical syntheses. Thesame materials as described above may be used for other embodiments ofthe present invention.

Now, a structure of the pest controller 1 will be described belowfurther in detail, referring to FIG. 2.

The container body 11 is of a cylindrical shape having an opening 15 ata distal end (upper part in FIG. 2A), and a portion 16 with reduceddiameter in a trunk of the distal end, an outside diameter of theportion 16 with reduced diameter being smaller than that of a proximalend. The portion 16 with reduced diameter has a body-side projection 17provided circumferentially, that contacts closely to the inner surfaceof the cap 10 in case of installing.

As seen in FIG. 2, the container body 11 has an inner space 19 with awick 18. The wick 18 is of a cylindrical shape, and consists essentiallyof a wick cover 20 and a fiber portion 21. The wick cover 20 is made ofresin film and of a cylindrical shape, and covers the fiber portion 21.The wick 18 functions as a liquid substance storage.

The fiber portion 21 is formed cylindrically by such fibers as polyesterfiber, polyacrylate fiber, and cotton, and is soaked with the chemicalsubstance 22 in which an active ingredient described below is dispersed.

That is, the fiber portion 21, which absorbs the chemical substance,functions as a substance retaining member.

The chemical substance 22 is liquid and contains at least one activeingredient with a pest-controlling effect and being volatilizable at anormal temperature. Typical examples of the volatile active ingredientthat is volatilizable at a normal temperature include pyrethroidcompounds such as empenthrin, 2,3,5,6-tetrafluoro-4-methoxymethylbenzyl3-(1-propenyl)-2,2-dimethylcyclopropanecarboxylate (hereinafter alsocalled as chemical substance (A)),2,3,5,6-tetrafluoro-4-methoxymethylbenzyl3-(2-methyl-1-propenyl)-2,2-dimethylcyclopropanecarboxylate,1-ethynyl-2-methyl-2-pentenyl3-(2-chloro-2-fluorovinyl)-2,2-dimethylcyclopropane-1-carboxylate,2,3,5,6-tetrafluoro-4-methylbenzyl3-(2-methyl-1-propenyl)-2,2-dimethyl-cyclopropanecarboxylate,2,3,5,6-tetrafluoro-4-methylbenzyl3-(2-chloro-2-fluorovinyl)-2,2-dimethylcyclopropanecarboxylate,2,3,5,6-tetrafluoro-4-methylbenzyl3-(1-propenyl)-2,2-dimethylcyclopropanecarboxylate,1-ethnyl-2-fluoro-2-pentenyl3-(2,2-dichlorovinyl)-2,2-dimethyl-cyclopropanecarboxylate,1-ethynyl-2-methyl-2-pentenyl3-(2,2-dichloro-vinyl)-2,2-dimethylcyclopropanecarboxylate,transfluthrin, terallethrin, furamethrin, tefluthrin, prallethrin, andallethrin, organophosphorus compounds such as fenitrothion anddichlorvos, carbamate compounds such as BPMC and metoxadiazone, juvenilehormone-like compounds such as methoprene and hydroprene,3,4-caranediol, N,N-diethyl-m-toluamide, p-menthan-3,8-diol, and plantessential oil such as hyssop oil.

These active ingredients are mostly liquid at a normal temperature andavailable as the above-identified chemical substances.

Further, the active ingredient used in the present invention preferablyhas the vapor pressure at 25° C. by Donovan method within a range of1×10⁻⁵ mmHg to 5×10⁻³ mmHg.

Donovan method is a method reported by Mr. Stephen F. Donovan in Newmethod for estimating vapor pressure by the use of gas chromatography:Journal of Chromatography A. 749, pp. 123-129 (1996).

Normally, an active ingredient being liquid at a normal temperature maybe used by filling in a container for holding the active ingredientsdescribed below, though it is possible to fill in the container 8 theliquid chemical substance diluted with one selected from a groupconsisting of alcohol such as ethanol and isopropyl alcohol, polyhydricalcohol such as polyethylene glycol, 1,3-butylene glycol, ethyleneglycol monobutyl ether, propylene glycol monomethyl ether, anddipropylene glycol monomethyl ether, hydrocarbon solvent such asisopentane, light isoparaffin, light liquid isoparaffin (IdemitsuPetrochemical: IP solvent 1620, 2028, 2835 Exxon Mobil: Isopar E, G, H,L, M), JIS first and second kerosene, and alkylbenzene, and esters suchas ethyl acetate, isopropyl myristate, diisopropyl adipate, and tributylacetylcitrate, or a mixture thereof.

The chemical substance 22 may be also added a colorant such as adyestuff. In this case, the use of a transparent container enables usersto readily know a rest of the substance 22 during use. Especially, asublimable dyestuff may be useful as a colorant of a pest controllerapplying the substance 22 to be used. More specifically, the colorantsublimates in using the substance 22, so that a pest-controlling effectcan be judged by ensuring a color of an applied spot. The colorant doesnot remain after use, so that the applied spot does not become dirty.

The container body 11 further includes a fiber bundle 23 adjacent to theopening 15.

The fiber bundle 23 is of substantially a columnar shape, a distal endbeing slant to have an angle relative to a vertical face to the axialdirection. An outer diameter of the fiber bundle 23 is substantiallyequal to an inner diameter of the opening 15. The fiber bundle 23penetrates the opening 15 in a fitting state. The fiber bundle 23,inside the container body 11, has a contacting portion 23 a forcontacting with the fiber portion 21 of the wick 18, and outside thebody 11, has an exposing portion 23 b exposed out of the opening 15.

In this embodiment, the fiber bundle 23 is a different member from thewick 18, though it may be the same member.

The cap 10 is attachable to the body 11. Attachment of the cap 10 makesthe exposing portion 23 b be covered, that is, the cap 10 becomes acover for sealing the exposing portion 23 b. On the other hand,detachment of the cap 10 makes the exposing portion 23 b be made open.

The cap 10 is attached to a distal end of the body 11, the outerdiameter of the cap 10 being substantially equal to that of the body 11.The inner diameter of thereof has two steps, which of an inner portion27 at a proximal end of the cap 10 is substantially equal to the outerdiameter of the portion 16 with reduced diameter of the body 11.Further, as seen in FIG. 2B, when the cap 10 is covered, the innerportion 27 at the proximal end of the cap 10 has a cap-side projection29 placed at slightly nearer to the proximal end than a placecorresponding to the body-side projection 17, and a sealing projection30 placed at a further distal end than a place corresponding to thebody-side projection 17. Therefore, when the cap 10 is covered on thebody 11, the body-side projection 17 is fixed after exceeding thecap-side projection 29, and further, the sealing projection 30 is fittedonto the portion 16 with reduced diameter of the body 11.

Next, a method for using the pest controller 1 will be described indetail below.

The cap 10 is removed at a spot for controlling insects to use the pestcontroller 1, so that the exposing portion 23 b is released from thesealing condition.

Since the fiber bundle 23 contacts with the wick 18 by thewick-contacting portion 23 a of the former and the fiber portion 21 ofthe latter, the chemical substance 22 is absorbed by capillarity up tothe exposing portion 23 b, thereby being exposed on the surface of theexposing portion 23 b. That is, in the present embodiment, the fiberbundle 23 has both functions of a substance lead-out member for leadingout the chemical substance and a substance exposing portion for exposingthe chemical substance on the surface of the body 11.

Consequently, when the cap 10 is removed, the chemical substance 22becomes contactable with open air and starts volatilizing. Empenthrin,an active ingredient with a pest-controlling effect, brings an excellentpest-controlling effect by volatilizing. At this time, as describedabove, the exposing portion 23 b functions as a substance releasingportion 25.

While an amount of the chemical substance 22 is released from theexposing portion 23 b, a further amount of the chemical substance 22 istransmitted to the exposing portion 23 b by capillarity. If and whenbeing reduced, the chemical substance 22 volatilizes from the exposingportion 23 b by the capillarity of the wick 18 and the fiber bundle 23until the chemical substance 22 in the container body 11 has been usedup. That makes it possible to use it up to the last.

Since the pest controller 1 includes the container 8, the length ofwhich is about 150 mm, and the clip 12, it may be readily hung on suchas a pocket of garments, so that it is convenient for carrying it.

The pest controller 1, as described above, is used for controlling pestsnot only by means of removing the cap 10 and releasing the chemicalsubstance 22, but also by means of application of the chemical substance22 on working suits or the like. More specifically, a top end 23 c ofthe fiber bundle 23 functions as a substance applicator 31. When thechemical substance 22 is applied on the suits by the substanceapplicator 31, empenthrin, an active ingredient, volatilizes from a spoton which the chemical substance 22 is applied, so as to bring apest-controlling effect.

It is also available to apply the chemical substance 22 on such as acloth and a paper, not limited to garments like working suits, and putthem on the spot for controlling pests. Further, for example, drawing acircle or an enclosure on a paper or a cloth, in which a foreign body tobe pest-controlled is placed, makes inside the enclosure apest-controlling atmosphere, thereby preventing pests from entering theenclosure.

The pest controller in the first embodiment is adapted to have thechemical substance 22 in the inner space 19 of the container body 11through the wick 18. However, it may be constituted only by a fiber anda chemical substance in the inner space 19 of the container body 11without the wick cover 20 of the wick 18 and also only by a chemicalsubstance. Further, it may be constituted in such a manner having athrough-hole in a part of the wick cover 20 so as to volatilize achemical substance. The wick 18 may be hardened by use of resin or thelike.

These pest controllers may be used again by filling the chemicalsubstance 22 in case of using up the chemical substance 22. In the case,it is economical to be able to use the container body 11 many times Itmay be also referred to have a structure of a cartridge replacement typeof the wick 18.

In the embodiment, the exposing portion 23 b as the substance releasingportion 25 and the top end 23 c as the chemical applicator 31 are madeof fiber, but they may be only a member transmittable of the chemicalsubstance 22, that is, a porous body or a resin precast product having ahollow through-hole may be employed as materials for the exposingportion 23 b and the top end 23 c.

Further, a container 9 having a structure shown in FIG. 3 may beemployed. More specifically, the container 9 includes a container body70 and a cap 71. A portion 16 with reduced diameter of the body 70 has aside hole 72 slightly longer in an axial direction and communicatinginside with outside. The cap 71 has a side hole 73 slightly longer in anaxial direction and communicating inside with outside. The innerdiameter of the cap 71 is substantially equal to the outer diameter ofportion 16 with reduced diameter of the body 70. The cap 71 is adaptedto be attachable to the body 70 by turning by a screw 75. A distal endof the body 70 exposes a fiber bundle 23 that is soaked with thechemical substance 22 in the body 70.

The use of the pest controller employing the container 9 shown in FIG. 3facilitates an adjustment of volatile amount of the chemical substance22. More specifically, changing of an angle of the body 70 and the cap71 changes a relative position between the side hole 72 of the body 70and the side hole 73 of the cap 71.

When the positions of the side holes 72 and 73 correspond to each other,effective areas of the holes communicating with inside and outside ofthe container 9 are wide, thereby achieving a high volatility. When thepositions do not correspond to, the areas are small, resulting in a lowvolatility. The areas may be adjusted in stepless fashion.

In other words, the present embodiment has a window, which is changeableof its opening area, constituted by the side holes 72 and 73 at thedistal end of the container 9.

As well as the pest controller 1 in the first embodiment of the presentinvention, it may be used by removing the cap 71 or by applying thechemical substance 22.

Still further, as seen in FIGS. 4, 5 and 6, the present invention mayemploy a container body without a substance retaining member.

In other words, in a container body 11 a shown in FIG. 4, the chemicalsubstance 22, which is liquid, is directly filled in an inner space 19of the body 11 a without the substance retaining member. As well as thecontainer body 11 of the pest controller 1 in the first embodiment, afiber bundle 23 is provided at an opening 15 of a top of the body 11 a.A valve system 50 is also provided between a proximal end of the fiberbundle 23 and the chemical substance 22, normally the valve system 50being closed. Pushing the fiber bundle 23 in a direction of the proximalend opens the valve system 50, so that the chemical substance 22 in theinner space 19 is volatilizable through the fiber bundle 23.

More specifically, the valve system 50 is provided with a valve body 50b movably in a valve chamber 50 a, the valve body 50 b being pressed bya spring 50 c in a direction of a valve seat 50 d. Pushing the fiberbundle 23 in a direction of the proximal end moves the valve body 50 badjacent thereto to resist the spring 50 c, so as to open the valve byleaving from the valve seat 50 d.

In case of using the pest controller in the embodiment, the chemicalsubstance 22 filled in the inner space 19 of the body 11 a is led out bypushing the fiber bundle 23 to open the valve system 50, therebyensuring that the chemical substance 22 in the inner space 19 istransmitted through the fiber bundle 23 to the distal end of fiberbundle 23 so as to volatilize outside.

The pest controller employing the container body 11 a holds a largeamount of the chemical substance 22 as it dispenses with the substanceretaining member, thereby being used for a long time. Further, pushingto open the valve system 50 leads a necessary amount of the chemicalsubstance 22 out to the distal end of the fiber bundle 23 that is asubstance exposing portion, resulting in making a desired amount of thechemical substance 22 volatilize.

Still further, a modified embodiment of a container body will bedescribed in detail below.

A container body 11 b shown in FIG. 5 directly holds a chemicalsubstance 22 in an inner space 19 of the body 11 b as it dispenses witha substance retaining member as well as the container body 11 a. Thebody 11 b includes a holder 53 and a cylindrical container 54.

The holder 53 is substantially of a cylindrical shape and is providedwith an opening 15 at a distal end, a through-hole 56 leading from theopening 15 and facing to an axial direction therewithin, and anintermediate wick 56 a, which functions as a substance lead-out member,therewithin.

The outside of holder 53 has a step portion 55 that is sectionallypectinate. The step portion 55 has an outer pressure adjusting portion57 a communicating with outside and an inner pressure adjusting portion57 b communicating with inside. The holder 53 is inserted into thedistal end of the cylindrical container 54 and fixed by a fixing member53 a.

The inner pressure adjusting portion 57 b functions as a temporaryreceptacle, that is, depending on a pressure change in the container, achemical substance is received at the temporary receptacle in case of ahigh pressure, thereby restricting an unnecessary volatilization of thechemical substance.

The opening 15 holds a resin mold part 51 that is a porous body. Theresin mold part 51 has a gap, so that the chemical substance 22 passesthrough the resin mold part 51 so as to penetrate the inside and outsideof container.

In case of using the pest controller, the chemical substance 22 isabsorbed in the resin mold part 51 by turning the top downwardly, is ledout by a porous structure of the resin mold part 51, and exposes to thedistal end of the resin mold part 51, so as to volatilize it bycontacting with air. The pest controller employing the container body 11b holds a large amount of the chemical substance 22 as it dispenses withthe substance retaining member, thereby being used for a long time.Further, due to the step portion 55, even if the chemical substance 22or air inside the inner space 19 expands with a change of temperature inthe inner space 19, the chemical substance 22 moves to the step portion55 so as to be received therein, or the air gradually flows through theouter and inner pressure adjusting portions 57 a and 57 b so that aninner pressure is lowered, thereby ensuring that the chemical substance22 does not voluminously creep out of the opening 15.

Still another embodiment of a container body will be described in detailbelow.

A container body 11 c shown in FIG. 6 directly holds a chemicalsubstance 22 in an inner space 19 of the body 11 c as it dispenses witha substance retaining member as well as the container body 11 a. Thecontainer body 11 c further includes a fiber bundle 23 at a distal endof an opening 15 as well as the container body 11 a. There is providedwith a valve system 50 consisting essentially of a ball 60 and a biasingmember 61 between a proximal end of the fiber bundle 23 and the chemicalsubstance 22. The ball 60 is biased toward the distal end by the biasingmember 61 and closes an opening 64 provided at the distal end of thevalve system 50, normally the valve system 50 being closed. When thevalve system 50 is closed, the chemical substance 22 inside thecontainer body 11 does not leak outside.

Pushing the fiber bundle 23 in a direction of a proximal end opens thevalve system 50, so that the chemical substance 22 in the inner space 19turns volatilizable through the fiber bundle 23. More specifically,moving the ball 60 in a direction of the proximal end by applying agreater force than a biasing force of the biasing member 61 to the fiberbundle 23 opens the valve system 50. The container body 11 c furtherincludes a tail stopper 62 at the proximal end and a follower 63 betweenthe tail stopper 62 and the chemical substance 22. The follower 63 ismade of resin and provided at the proximal end of the chemical substance22.

In case of using the pest controller, the chemical substance 22 is letvolatilize by pushing the fiber bundle 23. The pest controller employingthe container body 11 c holds a large amount of the chemical substance22 as it dispenses with the substance retaining member, thereby beingused for a long time. Further, in the container body 11 c, the follower63 moves to the distal end depending on a reduction of the chemicalsubstance 22. Therefore, that brings less deterioration of the chemicalsubstance 22 because it does not contact with air.

Next, a second embodiment of the present invention will be describedbelow.

A pest controller 4 in the second embodiment of the invention, shown inFIG. 7, holds a solid chemical substance 41 and includes a container 34,which consists essentially of a container body 36 and a cap 35.

Structure inside the pest controller 4 will be described in detailbelow, making reference to FIGS. 7-10.

The container body 36, as seen in FIG. 10, is of a cylindrical shapehaving an opening 15 at a distal end and a portion 16 with reduceddiameter at a trunk of the distal end. The outer diameter of the portion16 with reduced diameter is smaller than that of the proximal end. Thebody 36, as seen in FIG. 10C, further includes ribs 44 in an axialdirection therewithin.

The body 36 still further includes a propelling portion 37, which is ofa disc shape having a threaded rod at its center and is attached to theproximal end of the body 36 with being turnable.

The propelling portion 37 consists essentially of an operating portion38 and a threaded rod 39 (i.e. screw). The operating portion 38 isexposed outside and turnable relative to the body 36. The threaded rod39 has a spiral projection and the length of the threaded rod 39 isslightly shorter than that of the body 36.

The body 36 holds a chemical substance 41 therewithin. Referring to FIG.10B, the chemical substance 41 is of a cylindrical shape having a cavitytherewithin. The chemical substance 41 has the same active ingredient asthe pest controller 1 in the first embodiment. The chemical substance 41is formed in a particular shape in semisolid or solid state. In use of aliquid active ingredient, a particular shape is formed by such as agelling agent or a solid additive.

The body 36 has a movable member 42 at a proximal end of the chemicalsubstance 41. The movable member 42 has a threaded hole 47 at its centerin mesh with the threaded rod 39, and grooves 46 engaging with the ribs44 in an axial direction at an outside thereof.

The chemical substance 41 inserted in the container body 36 is propelledout by turning the propelling portion 37. That is, the threaded rod 39is inserted into the threaded hole 47 of the movable member 42, and thegrooves 46 are engaged with the ribs 44. Consequently, turning theoperating portion 38 of the propelling portion 37 turns the threaded rod39. Hence, an engagement of the ribs 44 and the grooves 46 prevent thebody 36 and the movable member 42 from turning, so that the movablemember 42 moves in an axial direction in a pitch of the threaded rod 39.In other words, a force generated by the threaded rod 39 makes thechemical substance 41 be propelled out of the body 36.

The cap 35, as seen in FIG. 10A, is attached to a distal end of the body36, the outer diameter of the cap 35 being substantially equal to thatof the body 36. The inner diameter has two steps, which of an innerportion 48 at a proximal end is substantially equal to the outerdiameter of the portion 16 with reduced diameter of the body 36.

The cap 35 is attachable to the body 36. Attachment of the cap 35 sealsfurther distal end than the portion 16 with reduced diameter of the body36. Thus, the opening 15 is sealed with the cap 35 and released withoutthe cap 35, so that the chemical substance 41 is exposed out of the body36. That is, the chemical substance 41 comes in contact with air.

Next, a method for using the pest controller 4 will be described indetail below.

Removing the cap 35 at a spot for controlling pests releases the opening15 of the body 36 from the sealing condition. Then turning thepropelling portion 37 propels the chemical substance 41 out. As seen inFIG. 9, an active ingredient volatilizes by exposing the faces of topand side of the chemical substance 41. In the embodiment, the faces oftop and side of the substance 41 functions as a substance releasingportion 25. Since the active ingredient has a pest-controlling effectand is volatilizable at a normal temperature, the active ingredientvolatilizes and brings an excellent pest-controlling effect. Changing alength of the chemical substance 41 that is propelled out changes anarea of the substance releasing portion 25, thereby readily changing alevel of the pest-controlling effect. Further, the faces of top and sideof the chemical substance 41 of the pest controller 4 may function as achemical applicator 31.

A propel-out system of the invention may employ the known propel-outsystem that is not the one in the pest controller 4 in the secondembodiment, or may not employ a rotary type.

Next a third embodiment of the present invention will be described indetail below.

A pest controller 5 in the third embodiment of the present invention isillustrated in FIGS. 11 and 12. The pest controller 5 includes asubstance releasing member 85 and a holder 86 for holding the substancereleasing member 85 at a top of a fiber bundle 23. Structure except theholder 86 and the substance releasing member 85 is the same as thestructure of the pest controller 1 shown in FIG. 2, so that detaileddescription on those members depicted with the same reference numeralsas the pest controller 1 will not be repeated hereinafter.

The substance releasing member 85 is of a tabular shape and separatelyprovided. Preferably, the substance releasing member 85 is made of sucha material that readily absorbs a liquid by capillarity, such as paperthat is made of fine fiber, or a body with a number of small halls. Anarea and a thickness of the substance releasing member 85 may beselected properly, the latter being in such a range in which the memberis held between the holder 86 described below. The substance releasingmember 85 has a flexibility, which makes it so compact as to be readilycarried by winding up or folding it during non-use.

The holder 86 is specifically a slit situated on a top of the fiberbundle 23. The face of the slit is parallel with the axis of the pestcontroller 5.

In case of using the pest controller 5, as seen in FIG. 12, thesubstance releasing member 85 is to be placed in the holder 86 of thefiber bundle 23. The chemical substance 22 absorbed into the distal endof the fiber bundle 23 further infiltrates in to the substance releasingmember 85, thereby volatilizing from the substance releasing member 85.

By the pest controller 5 with the structure described above, the widerarea of the substance releasing member 85 is made, the wider area thechemical substance 22 volatilize from. Referring to FIG. 11, duringnon-use, attachment of the cap 10 to the container body 11 prevents thechemical substance 22 from volatilizing and it is also possible to makethe substance releasing member 85 to a portable size.

Further, a fourth embodiment of the present invention will be describedin detail below.

A pest controller 6 in the fourth embodiment of the invention isillustrated in FIGS. 13-16. The pest controller 6 includes a containerbody 11 and an attachment 87 attachable to the body 11. In theembodiment, the attachment 87 functions as both a cap and a substancereleasing member. Structure of the pest controller 6 except theattachment 87 and a connecting portion of the body 11 to the attachment87 is the same as the structure of the pest controller 1 shown in FIG.2, so that detailed description on those members depicted with the samereference numerals as the pest controller 1 will not be repeatedhereinafter.

The attachment 87, both the cap and the substance releasing member, isof a cylindrical shape and has an opening 88 on a trunk thereof.Opposite ends 90 a and 90 b of a tube of the attachment 87 are both openand attachable to the body 11. The attachment 87 is provided with aseparator 89 for dividing the end 90 a and the end 90 b.

The attachment 87 is provided with a substance releasing member 91within a space enclosed by the separator 89, the trunk of the opening88, and the end 90 a. Preferably, the substance releasing member 91 ismade of such material that readily absorbs a liquid by capillarity andthat is apt to act capillarity, for example, made of fiber or with anumber of small halls. The substance releasing member 91 has elasticity.In case of attaching the attachment 87 to the end 90 a of the body 11,the substance releasing member 91 is pushed to be dented by a top of thefiber bundle 23, thereby ensuring that the top of the fiber bundle 23comes into contact with the substance releasing member 91.

The substance releasing member 91 communicates with the outside ofattachment by the opening 88 so as to release the chemical substance 22absorbed into the substance releasing member 91.

In case of using the pest controller 6, as seen in FIGS. 15 and 16, theend 90 a of the attachment 87 is to be attached to the body 11. Thechemical substance 22 absorbed into the distal end of the fiber bundle23 further infiltrates in to the substance releasing member 91. Thus,the chemical substance 22 absorbed into the substance releasing member91 volatilizes from the opening 88.

During non-use, as seen in FIGS. 13 and 14, the end 90 b of theattachment 87 is to be attached to the body 11. Thereby, the distal endof the fiber bundle 23 is sealed with the trunk of the attachment 87 andthe separator 89, so as to prevent the chemical substance 22 fromvolatilizing.

The pest controller 6 is easy to carry due to the attachment 87 attachedto the body 11 during both use and non-use.

Next, fifth and sixth embodiments of the present invention will bedescribed in detail.

Pest controllers 7 and 7 a in the fifth and sixth embodiments areadapted to apply a chemical substance by a rolling body such as a ball92 and a roll 93.

The pest controller 7 in the fifth embodiment of the invention isillustrated in FIG. 17. The pest controller 7 includes a container body11 and the ball 92 held rotatably to the body 11. It is constructed insuch a manner that the chemical substance 22 held in the body 11 isadhered to the ball 92. In the embodiment, the ball 92 functions as asubstance applicator 31.

In case of using the pest controller 7, the chemical substance 22 isapplied to a spot for controlling pests by removing a cap 10 and thenmoving the ball 92 with contacting the spot. More specifically, the ball92 rotates adhering the chemical substance 22, thereby applying thechemical substance 22 to a part with which the ball 92 contacts. Then,the chemical substance 22 controls pests by volatilizing.

The pest controller 7 a in the sixth embodiment of the invention isillustrated in FIG. 18. The pest controller 7 a includes a containerbody 11 and the roll 93 held rotatably to the body 11. It is constructedin such a manner that the chemical substance 22 held in the body 11 isadhered to the roll 93. In the embodiment, the roll 93 functions as asubstance applicator 31.

In case of using the pest controller 7 a, the chemical substance 22 isapplied to a spot for controlling pests by removing a cap 10 and thenmoving the roll 93 with contacting the spot. More specifically, the roll93 rotates adhering the chemical substance 22, thereby applying thechemical substance 22 to a part with which the roll 93 contacts. Then,the chemical substance 22 controls pests by volatilizing.

Further, it may be possible, as a pest controller 7 b in a seventhembodiment of the present invention, to heat the proximity of asubstance releasing portion 25 in order to readily volatilize a chemicalsubstance 22 further more during use.

Referring to FIG. 19, the pest controller 7 b includes an electricheater 95, a battery 96, leads 97 and a switch 98. The opposite poles ofbattery 96 are connected through the leads 97 to the heater 95. Onlywhen the switch, which is positioned intermediately of a lead 97, isturned on, the heater 95 is heated. The heater 95 is placed adjacent toa distal end of a fiber bundle 23. In case of using the pest controller7 c, turning on the switch 98 heats the distal end and its proximity bythe heater 95, thereby facilitating volatilization of a chemicalsubstance 22 from the fiber bundle 23. A pest controller including asubstance releasing portion 25 may be used as a pest controller of itshigh volatility by heating the substance releasing portion 25 and itsproximity.

It is further possible that a part in which a chemical substance 22 isheld within a container body 11 is to be adapted to be pressed so as tofacilitate an application or a release of the chemical substance 22. Inother words, a press of the part in which the chemical substance 22 isheld causes a pressure difference between the atmospheric and the innerpressures, thereby facilitating a release of the chemical substance 22.Specifically, a deformable container may be employed as the containerbody 11 so that the volume of the part in which the chemical substance22 is held is decreased by hand-grasping or the inner pressure of thebody 11 may be increased by high pressure filling of the body 11 itselfor a cartridge held within the body 11 and holding the chemicalsubstance 22.

The pest controllers adapted to press the part in which the chemicalsubstance 22 is held include pest controllers 100, 101, and 106.

The pest controller 100 in an eighth embodiment, as seen in FIG. 20, acontainer body 111 directly holds a chemical substance 22. The body 111is made of soft resin and deformable by being compressed from outside.The body 111 includes a substance lead-out tube 112 therewithin. Thesubstance lead-out tube 112 is provided with a valve system 113 at adistal end, and is open at a proximal end into which the chemicalsubstance 22 in the body 111 is flown. The valve system 113 is normallyclosed, but is adapted to open in response to a rise of a pressure ofthe substance lead-out tube 112 side. In a closed condition of the valvesystem 113, the body 111 is airtight.

A fiber bundle 23 is provided at a distal end of the valve system 113.When the valve system 113 is open, the chemical substance 22 istransferred from the inside of body 111 through the substance lead-outtube 112 to the fiber bundle 23, being supplied to the fiber bundle 23.

In case of using the pest controller 100, a distal end of the fiberbundle 23 functions, as well as the pest controller 1, as a substancereleasing portion 25 and a substance applicator 31. In case of supplyingthe chemical substance 22 to the fiber bundle 23, users press to deformthe body 111 from outside with a distal end of the pest controller 100upwardly. Then, as the volume of body 111 is decreased, an innerpressure thereof rises, and the pressure of the substance lead-out tube112 side of the valve system 113 rises, thereby ensuring that the valvesystem 113 is open. Thus, the chemical substance 22 of the body 111 issupplied to the fiber bundle 23, so as to volatilize and apply thechemical substance 22 further more.

Referring to FIG. 21, a pest controller 101, a modification of the pestcontroller 100 in the eighth embodiment, has a structure wherein asubstance lead-out tube 112 is only different from that of the pestcontroller 100. More specifically, as seen in FIG. 21, a substancelead-out tube 115 is provided with double tubes consisting of an innertube 116 and an outer tube 117. The outer tube 117 has a substanceintroduction hole 118 at a distal end thereof, whereby a chemicalsubstance 22 inside a body 111 flows between the outer and inner tubes117 and 116 of the substance lead-out tube 115.

The substance lead-out tube 115 has a sealing stopper 120 at a proximalend thereof for sealing a proximal end of the outer tube 117. There isformed with a space 121 between the sealing stopper 120 and the innertube 116, whereby the chemical substance 22 flows from a space betweenthe outer and inner tubes 117 and 116 to a cavity in the inner tube 115.

In case of supplying the chemical substance 22 to the fiber bundle 23, auser of the pest controller 101 presses and deforms the body 111 fromoutside with a distal end of the pest controller 101 downwardly. Then,as the volume of body 111 is decreased, an inner pressure thereof rises,and the pressure of the substance lead-out tube 115 side of a valvesystem 113 rises, thereby ensuring that the valve system 113 is open.Thus, the chemical substance 22 of the body 111 is supplied to the fiberbundle 23, so as to volatilize and apply the chemical substance 22further more. Since the chemical substance 22 is supplied to the fiberbundle 23 with the distal end of the pest controller 101 downwardly, thechemical substance 22 may be applied with adjusting an amount of thechemical substance 22, so as to make it possible to apply a properamount of the chemical substance 22.

A pest controller 106 in a ninth embodiment, as seen in FIG. 22,includes a pressurizer 150 and holds a chemical substance 22 directly ina container body 11 a. A container body 106 a of the pest controller 106employs a same structure as the container body 11 a shown in FIG. 4, sothat detailed description on those members depicted with the samereference numerals as the container body 11 a will not be repeatedhereinafter.

The pressurizer 150 is provided with a pressurizing chamber 151, a valvemember 152, and a biasing member 153. The pressurizing chamber 151 has athrough-hole 155 leading outside, which is formed on a top of a proximalend of the pest controller 106. The valve member 152 is placed betweenthe pressurizing chamber 151 and the inside of body 11 a. The valvemember 152 is normally biased toward the pressurizing chamber 151 by thebiasing member 153 so as to maintain an airtightness therebetween. Ifand when a pressure of the pressurizing chamber 151 becomes higher thanthe inner pressure of the body 11 a and a force by the pressuredifference becomes bigger than a biasing force of the biasing member153, the valve member 152 is released of its airtightness, therebyensuring that a gas in the pressurizing chamber 151 flows from thepressurizing chamber 151 into the body 11 a.

The pressurizing chamber 151 is elastic and deformable.

In case of using the pest controller 106, the fiber bundle 23 is pressedto volatilize the chemical substance 22. In case of making its amountmore, the chemical substance 22 is supplied further more by thepressurizer 150.

More specifically, the pressurizing chamber 151 is pushed with thethrough-hole 155 closed. Deformation of the pressurizing chamber 151,which has elasticity, decreases the volume of the pressurizing chamber151, so that the pressure in the pressurizing chamber 151 rises.

The pressure in the pressurizing chamber 151 rises and becomes higherthan the inner pressure of the body 11 a, the valve member 152 beingreleased of its airtightness, thereby ensuring that a gas in thepressurizing chamber 151 flows from the pressurizing chamber 151 intothe body 11 a. On ceasing to push the pressurizing chamber 151, thevalve member 152 is moved back by the biasing member 153 to make anairtight condition again and the inner pressure of the body 11 a rises.

Further, in a state of high pressure of the body 11 a, pushing the fiberbundle 23 toward a proximal end opens the valve system 50, therebytransferring the chemical substance 22 in an inner space 19 to the fiberbundle 23, but it is possible to supply the chemical substance 22further more to the fiber bundle 23 due to a high pressure of the insideof body 11 a. If necessary, a repeat of pushing the pressurizing chamber151 enables the inner pressure of the body 11 a to raise more.

A pest controller 102 in a tenth embodiment of the present invention, asseen in FIG. 10, may be used.

A wick 128 of the pest controller 102, different from the wick 18 of thepest controller 1 in the first embodiment, directly holds a chemicalsubstance 22 in a tube 129. There is provided with a follower 130movable depending on a consumption of the chemical substance 22 at aproximal end of the chemical substance 22, thereby preventing it fromleaking from the proximal end so as to use up the chemical substance 22to the last. Herein, the follower 130 is a gel of high viscosity.

Eleventh, twelfth and thirteenth embodiments are now described in detailbelow. Pest controllers 103, 104 and 105 in these embodiments employchemical substances 41 of solid as well as the pest controller 4 in thesecond embodiment. The pest controllers 103, 104 and 105 each include acap 10, though they may be constituted as they dispense with the cap 10.

The pest controller 103 in the eleventh embodiment, as seen in FIG. 24,includes the chemical substance 41, the cap 10, a rolled paper 131 and areleasing string 132. The chemical substance 41 is of a columnar shapeand rolls up the rolled paper 131. The releasing string 132 is placedbetween the rolled papers 131, which is released gradually by pullingthe releasing string 132.

In case of using the pest controller 103, using of a distal end of thechemical substance 41 as a substance releasing portion 25 volatilizes anactive ingredient from the distal end of the chemical substance 41 tocontrol pests. Or using of the distal end of the chemical substance 41as a substance applicator 31 volatilizes an active ingredient to controlpests by contacting the distal end of the chemical substance 41 with aspot for controlling pests.

According as its use, the chemical substance 41 is reduced and anexposing portion becomes small, resulting in a decrease of an amount ofvolatilization of an active ingredient and a difficulty in applicationof the chemical substance 41. However, by the pest controller 103,pulling the releasing string 132 gradually removes the rolled paper 131to change an exposing area, thereby enabling a required exposing area ofthe chemical substance 41.

The pest controller 104 in the twelfth embodiment of the invention, asseen in FIG. 25 includes the chemical substance 41, a propelling portion133, a container body 11 and the cap 10. The propelling portion 133consists essentially of an operating portion 135 and a threaded rod 136(i.e. screw).

The operating portion 135 is of a cylindrical shape and is engaged withthe threaded rod 136 with the portion 135. The threaded rod 136 is of astick shape and has a spiral projection 136 a. The operating portion 135is turnable relative to the body 11. The threaded rod 136 is adapted tobe propelled out and in by turning the operating portion 135.

The chemical substance 41 is held at a distal end of the threaded rod136, and moves in response to the threaded rod 136 propelled out and in,so as to be able to propel the chemical substance 41 out.

In case of using the pest controller 104, as well as the pest controller103 in the eleventh embodiment, the distal end of the chemical substance41 is to be used as a substance releasing portion 25 or a substanceapplicator 31 to volatilize an active ingredient for controlling pests.

According as its use, the chemical substance 41 is reduced and anexposing portion becomes small, resulting in a decrease of an amount ofvolatilization of an active ingredient and a difficulty in applicationof the chemical substance 41. However, by the pest controller 104,turning the operating portion 135 propels the chemical substance 41 outfor getting a required exposing area of the chemical substance 41.

The pest controller 105 in the thirteenth embodiment of the invention,as seen in FIGS. 26 and 27, includes the chemical substance 41, apropelling portion 139, a biasing member 140, a knocker 143, a containerbody 11 and the cap 10.

The propelling portion 139 consists essentially of a substance retainingtube 142 and a chuck 144. The substance retaining tube 142 is of acylindrical shape and provided with a taper 142 a whereby an outerdiameter becomes larger as toward a distal end. The outer circumferenceof the taper 142 a engages with the chuck 144 to press the substanceretaining tube 142 inside. The chemical substance 41 is positionedinside the substance retaining tube 142 and exposed from an opening 145of the body 11.

The substance retaining tube 142 is biased toward a proximal end by thebiasing member 140. Referring to FIG. 27A, in which this state isillustrated, the chuck 144 is engaged with and pressed by the taper 142a of the substance retaining tube 142. The chemical substance 41 is heldin the substance retaining tube 142.

Pushing the knocker 143 with a stronger force than the biasing member140 lets the substance retaining tube 142 move forward toward the distalend, thereby letting the chemical substance 41 move forward.

Moving the knocker 143 further forward makes the chuck 144 come incontact with an inner projection 141 of the body 11, so that only thesubstance retaining tube 142 moves forward, and as seen in FIG. 27B, theengagement of the taper 142 a with the chuck 144 is released. Then, theforce on the knocker 143 being loosened, the knocker 143 moves backwardby a force of the biasing member 140, but the chemical substance 41 doesnot move back because the engagement with the chuck 144 is released.

In order to move the chemical substance 41 back to accommodate it in thebody 11, the chemical substance 41 is to be pushed toward the proximalend with pushing the knocker 143. The engagement with the chuck 144 ofthe taper 142 a is released so as to be in an open state, so that thechemical substance 41 is accommodated readily.

Thus structure of the pest controller 105 enables a propelling-out andan accommodation of the chemical substance 41.

In case of using the pest controller 105, as well as the pest controller103 in the eleventh embodiment, the distal end of the chemical substance41 is to be used as a substance releasing portion 25 or a substanceapplicator 31 to volatilize an active ingredient for controlling pests.

According as its use, the chemical substance 41 is reduced and anexposing portion becomes small, resulting in a decrease of an amount ofvolatilization of an active ingredient and a difficulty in applicationof the chemical substance 41. However, by the pest controller 105,pushing the knocker 143 propels the chemical substance 41 out forchanging the exposing area of the chemical substance 41. If the knocker143 is not pushed, the chuck 144 prevents the chemical substance 41 frommoving back.

Still further, pest controllers as described below may be constituted bya container adapted to be directly worn and/or attached to clothes. Or acontainer may also have an attaching member with which the pestcontroller is adapted to be attachable to such foreign body as clothesand an outdoor tent. Or without such a member as referred to as “acontainer” in usual meaning, a pest controller may be constituted onlyby a substance exposing portion.

A pest controller 200 in a fourteenth embodiment of the invention isillustrated in FIG. 31. The pest controller 200 includes a containerbody 202 of a disc shape and a substance retaining member 201 forholding a chemical substance 22. The body 202 consists essentially of alid 203 and a base 204, which are substantially of the same size.Putting the lid 203 and the base 204 together forms a sealed cavitytherewithin, wherein a substance retaining member 201 is provided.

As to the pest controller 200, the substance retaining member 201 isused as a substance exposing portion. More specifically, using thesubstance retaining member 201 as a substance releasing portion 25 or asubstance applicator 31 volatilizes an active ingredient contained inthe chemical substance 22 for controlling pests. Further, the lid 203functions as a cover for sealing the substance exposing portion.

The pest controller 200, as seen in FIG. 31B, further includes anattaching member 208 on a back of the body 202. The attaching member 208allows the pest controller 200 to be attachable to users' clothes.Therefore, users may attach the pest controller 200 on their clothes soas to readily carry the pest controller 200. Herein, the attachingmember 208 may be the known materials, which only have to be attachableto clothes such as an adhesive substance, a surface fastener and asafety pin. The attaching member described above is used for the pestcontroller in any other embodiment.

A pest controller 210 in a fifteenth embodiment of the invention isillustrated in FIG. 32. The pest controller 210 includes a containerbody 212 of a tabular or disc shape, the surfaces of which are ofcircular shape, and a substance retaining member 211 holding a chemicalsubstance 22. The body 212 has an opening 215 formed on one surfacethereof and a lid 214 covering the opening 215. The lid 214 is adeformable sheet and covers the opening 215 by such as an adhesivesubstance so as to seal up the inside of container.

In case of using the pest controller 210, as seen in FIG. 32, byremoving the lid 213 as pulling it out, the opening 215 is released.Then the chemical substance 22 held in the substance retaining member211 provided inside the body 212 volatilizes from the opening 215.

The lid 213 has a smaller area than the body 212 and looks like a partof the surface of the body 212, but it is also possible, as a pestcontroller 210′ shown in FIG. 33, to include a lid 213 with which thewhole area of a surface of a container body 212 is covered.

The pest controller 210′ is of a thin badge shape and has no specialmember referred to as “a container” in usual meaning. The pestcontroller 210′ includes a main body 190, which holds and exposes achemical substance absorbed through its surface. The surface of mainbody 190 is covered with a thin sheet 191, whereby an exposing face ofthe chemical substance is covered. That is, the embodiment uses thedeformable sheet 191 as a cover, with which a substance exposing portionis covered, for example, with the aid of an adhesive substance. In useof the pest controller 210′, the sheet 191 is removed as pulling it out,so as to expose the substance exposing portion for volatilizing thechemical substance into open air.

The pest controller 210′ may also have an attaching member, not shown,to attach it to users' clothes or an outdoor tent.

Still further, pest controllers shown in FIGS. 34-43 may be available.By such controllers, it is easy for users to directly wear and/or attachto clothes and carry them. Further, the controllers are seemingly ofwearing such as ornaments so as to be used without sense ofincompatibility. A position for wearing them may be any of body partsconsisting of a head, an arm, a finger, a trunk and a foot.

The pest controllers shown in FIGS. 34-43 each include a containeraccommodating a chemical substance 22 therewithin, wherein a substanceexposing portion is sealed by a cover, so as to volatilize an activeingredient contained in the chemical substance 22 for controlling pestswhen the controllers are used.

More specifically, a pest controller in a sixteenth embodiment in FIG.34 is of a ring shape and includes a container 220 a, the inner space ofwhich is sealed with a lid 220 b.

A pest controller 221 shown in FIG. 35 is of a bracelet shape, availableas a bracelet, and includes a container 221 a of a tubular shape, theinner space of which is sealed with a lid 221 b.

Pest controllers 240, 250, and 260 in twenty-sixth, twenty-seventh, andtwenty-eighth embodiments shown in FIGS. 44-48 may be available. Thecontrollers 240, 250, and 260 each are portable and accommodatetherewithin a chemical substance 22 containing an active ingredient witha pest-controlling effect against harmful pests for human body and beingvolatilizable at a normal temperature.

The pest controller 240 in the twenty-sixth embodiment, as seen in FIG.44, is of a slightly thick sheet, and includes a sealing bag 241 and anair-permeable bag 242 that is put inside the sealing bag 241. Theair-permeable bag 242 is illustrated in FIG. 45.

The sealing bag 241 is made of such material as preventing a chemicalsubstance 22 from volatilizing outside, more specifically, being formedin a bag shape with a multi-layered film made of resin. The sealing bag241 covers the air-permeable bag 242, thereby maintain airtightness.

The air-permeable bag 242 is made of an air-permeable material, forexample, an unwoven cloth. The chemical substance 22 is accommodatedwithin and covered by the air-permeable bag 242. Consequently, thechemical substance 22 is movable outside the air-permeable bag 242. Morespecifically, as seen in FIG. 46, the air-permeable bag 242 is providedwith a substance absorbing member 243 being adapted to be soaked withthe liquid chemical substance 22, and accommodates the substanceabsorbing member 243 soaked with the chemical substance 22. Thesubstance absorbing member 243 is made of any material being absorbableof a liquid such as fiber and a porous member. The chemical substance 22contains an active ingredient with a pest-controlling effect againstharmful pests for human body and being volatilizable at a normaltemperature.

The pest controller 240 is thus constituted, thereby allowing thechemical substance 22 absorbed in the substance absorbing member 243 topass out of the air-permeable bag 242. However, in such a condition thatthe air-permeable bag is put in the sealing bag 241, a vapor of thechemical substance 22 is sealed by the sealing bag 241 and does nottranspire outside.

In case of using the pest controller 240, a part of the sealing bag 241it to be cut so as to take out the air-permeable bag 242 therewithin.Thereby, the chemical substance 22 inside the air-permeable bag 242transpires outside, the active ingredient controlling pests. Herein, thechemical substance 22 is accommodated within the air-permeable bag 242,so that the liquid chemical substance 22 does not disperse outside.Thus, the liquid chemical substance 22 does not contact directly with abody or the like.

The pest controller 250 in the twenty-seventh embodiment, as seen inFIG. 47, includes an air-permeable bag 252 that is different from thatof the pest controller 240 in the twenty-sixth embodiment.

More specifically, an adhesive member 253 is provided in a part of theair-permeable bag 252. That is, the whole surface of one side of theair-permeable bag 252 of sheet has an adhesive member 253, whereby thepest controller 250 is attachable to human body or clothes so as to beportable, or fixable to an outdoor tent or the like for controllingpests.

The pest controller 260 in the twenty-eighth embodiment, as seen inFIGS. 48 and 49, is of a bar shape and a portable size, and includes asealing bag 261 and a substance absorbing member 243. The substanceabsorbing member 243 is made of fibrous sheet adapted to be soaked witha liquid chemical substance 22. The substance absorbing member 243soaked with the chemical substance 22 is formed into a bar shape byrounding the sheet. Then, the substance absorbing member 243 of a barshape is put and sealed in the sealing bag 261. Herein, the chemicalsubstance 22 contains an active ingredient with a pest-controllingeffect against harmful pests for human body and being volatilizable at anormal temperature.

In case of using the pest controller 260, a part of the sealing bag 261it to be cut so as to release the sealing condition of the substanceabsorbing member 243 for controlling pests. For example, with a part ofthe sealing bag 261 cut, insert the pest controller 260 into a breastpocket, thereby the chemical substance 22 inside the bag transpiresoutside, an active ingredient controlling pests. The part of the pocketwhere the pest controller 260 is inserted is covered with a part of thesealing bag 261, so that the chemical substance 22 does not contactdirectly with clothes.

The chemical substances 22 and 41 may be active ingredients only, thougha solvent or an addictive may be added. Or, it is possible to enclose anactive ingredient in a microcapsule or the like to volatilize bycrushing it when applying the chemical substance. In this case, withoutthe caps 10 and 35, it is possible to prevent the active ingredient fromvolatilizing.

Pests being controllable by the pest controllers 1, 4, 5, 6, 7, 7 a, 7b, 100, 101, 102, 103, 104, 105, and 106 are, for example, as follows:

A pest-controlling effect by the pest controller 1 of the presentinvention will be further detailed below by the following test examples;however, the present invention is not limited to those examples.

EXAMPLE 1

(A Pest Controlling Effect by Volatilization of the Chemical Substance22 from the Substance Releasing Portion)

Test pest controllers (a) and (b) were made by the pest controller 1shown in FIG. 2 with chemical substance 22 containing compound (A)(2,3,5,6-tetrafluoro-4-methoxymethylbenzyl3-(1-propenyl)-2,2-dimethylcyclopropanecarboxylate, the vapor pressureat 25° C. by Donovan method: 1.4×10⁻⁵ mmHg) as an active ingredient.

The chemical substance 22 of the test controller (a) was a solution that2.0 g of compound (A) was mixed and dissolved with about 10 mg of acolor material, Sumiplast Blue OA, which was filled in the wick 18 bydropping. The chemical substance 22 of the test controller (b) was a 1.1g of solution that compound (A) mixed and dissolved with ethanol byweight ratio 1:1, and further mixed and dissolved with about 5 mg of acolor material, Sumiplast Blue OA, which was filled in the wick 18 bydropping.

On the other hand, female adult common mosquitoes (Culex pipienspallens) used for a tested pest were anaesthetized by carbon dioxide,and then a group of 10 mosquitoes was put into a cup 80 made of PET(having a bottom diameter of 8 cm, a lid diameter of 9.5 cm and a heightof 4.5 cm) shown in FIG. 28. The cup 80 had a hole 81 having a diameterof 3 cm at a center and a lid 83 provided with twelve small vents 82 asair holes. Then the lid 83 was attached to the cup 80, the hole 81 wascovered with a piece of cotton soaked with 1% sucrose solution, and thisstate was left sitting as it was so as to recover the anaesthetizedmosquitoes.

The test controllers (a) and (b) confirmed that the color materialreached the distal end of fiber bundle, the substance releasing portion25 and that the filled solution reached there. The controller wasinserted into a hole having a diameter of 6 mm opened at a center of afilter paper 84 having a diameter of 9 cm without the cap, and set byexchanging by the cotton so that the distal end of fiber bundle 23 waspositioned at a length of 3 cm into the cup from the lid surface. Thestate is illustrated in FIG. 29. After setting, the number of mosquitoesknocked down was counted at regular intervals. Further the same test wascarried out again.

As a pest controller used for comparison, the one in which only about 1g of ethanol was filled in the wick 18 by dropping was prepared and thesame test as described in Example 1 was carried out to count the numberof mosquitoes knocked down at regular intervals. The results are shownin Table 1.

The test controllers (a) and (b) both showed an apparent immediateeffect. TABLE 1 Number of female adult common mosquitoes knocked downafter after after after after 2 min. 4 min. 6 min. 8 min. 10 min.

EXAMPLE 2

(A Pest Controlling Effect by Volatilization of the Chemical Substance22 Applied by Means of the Substance Applicator 31 of the PestController 1)

Using the test pest controllers (a) and (b) made in the text example 1,test filter papers (a′) and (b′) were made. More specifically, at acenter of the filter paper 84 having a diameter of 9 cm, a circle havinga diameter of 3 cm was drawn by a pencil and the substance applicator 31of the test controllers (a) and (b) applied the substance by contactingwith the circle having a diameter of 3 cm. Herein, the chemicalsubstance 22 had a color material of blue, thereby being applied aspainting up the inside of the circle.

On the other hand, as described in test example 1, female adult commonmosquitoes used for a tested pest were anaesthetized by carbon dioxide,and then a group of 10 mosquitoes was put into a cup 80 made of PET(having a bottom diameter of 8 cm, a lid diameter of 9.5 cm and a heightof 4.5 cm) shown in FIG. 28.
